Urabrask the Hidden

Legendary Resistance (3/Day). If Urabrask fails a saving throw, he can choose to succeed instead.

Entropic Aura. A creature hostile to Urabrask that starts its turn within 30 feet of him must make a DC 21 Wisdom saving throw or suffer the effects of the slow spell until the start of its next turn.

Living Furnace. Each creature that starts its turn within 10 feet of Urabrask takes 5 (2d4) fire damage.

Pounce. If Urabrask moves at least 40 feet straight toward a creature and then hits it with a claw attack on the same turn, the target must succeed on a DC 21 Strength saving throw or be knocked prone. If the target is prone, Urabrask can make one bite attack against it as a bonus action.

Multiattack. Urabrask makes two attacks with his claws.

Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) slashing damage.

Bite. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 21 (3d10 + 5) piercing plus 10 (3d6) fire damage.

Tail. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 12 (2d6 + 5) bludgeoning damage. If the target is a creature, it must succeed on a DC 21 Strength saving throw or be pushed up to 15 feet away from Urabrask.

Noxious Charge (Recharge 5–6). Urabrask moves up to his movement speed and can move through the space of any creature Medium or smaller. The first time he enters each creature's space during this move, that creature must make a DC 21 Dexterity saving throw, taking 36 (8d8) bludgeoning or half as much on a success. A creature that fails its saving throw is knocked prone. This movement does not provoke attacks of opportunity.

During this charge, Urabrask's body emits industrial fumes that fill the space he moves through. The area the fumes occupy is heavily obscured, and they linger for 1 minute. When a creature starts its turn completely within the fumes or moves into them for the first time on each of its turns, it must make a DC 21 Constitution saving throw, taking 27 (6d8) poison damage on a failed save or half as much on a success. A moderate wind (at least 10 miles per hour) disperses the fumes after 4 rounds. A strong wind (at least 20 miles per hour) disperses them after 1 round.

Machine Cunning. Urabrask takes the dash, disengage, dodge, or hide action as a bonus action.

Urabrask can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Urabrask regains spent legendary actions at the start of his turn.

Detect. Urabrask makes a Wisdom (Perception) check.

Tail Attack. Urabrask makes a tail attack.

Slashing Charge (Costs 2 Actions). Urabrask moves up to his movement speed in a straight line and can move through the space of any creature Medium or smaller. The first time he enters each creature's space during this move, he can make a claw attack against that creature, dealing an additional 7 (2d6) slashing damage on a hit.
